Q2052Mark Twain was born on 30 November 1835, two weeks after Halley's Comet swung round the sun. In 1909 he said he expected to go out with it. He died on 21 April 1910 — one day after the comet's return.
As his biographer recorded it, Twain called himself and the comet 'two unaccountable freaks' who had come in together and must go out together. The dates in question are the comet's perihelions — its closest passes round the sun — which frame his life almost exactly: born a fortnight after one, gone a day after the next. Halley's returns roughly every 76 years; it is due again in 2061.
